摘要
经济器补气系统分为带闪发器的补气(FTVI)系统和带过冷器的补气(ICVI)系统,实验研究了R32ICVI系统的性能,并与R32FTVI系统性能进行了对比,得出室外温度大于2℃时,相比于两种补气系统,无补气系统性能更优;室外温度小于-5℃时,ICVI系统表现出更好的性能,当室外温度为-10℃时,COP增比为21. 41%。
The vapor-injected system can be divided into internal cooling( ICVI) and flash tank( FTVI) types. In this paper,the performance of the IC system of R32 is experimentally studied and compared with that of R32 FT system. It is concluded that when the outdoor temperature is greater than 2 ℃,the performance of the system without VI is better than that of the two systems with VI,when the outdoor temperature is less than-5 ℃,the performance of the ICVI is better,When the temperature is-10 ℃,the COP increase ratio is 21. 41%.
